M designates a pawl which is held normally 8o 3o The invention further consists in various in engagement with the ratchet-teeth on the details of construction and combination of head of the lever A when the tool is used in parts, dac., which will be hereinafter more the stretching of the wire. A spring N, bearfully described, and then specifically defined ing between said pawl and a projection P on in the appended claims. said curved segment, serves to normally hold 85 The invention is clearly illustrated Vin the the pawl in engagement with said ratchetaccompanying drawings, which, with the letteeth. ters of reference marked thereon, form a part Suitable wire-cutting means is provided by of this application, and in which drawings notching the two heads of theleversA and B, similarletters of reference indicate like parts as at T and T', causing the two faces of the 9c 4o of the several views, in whichheads to shear with each other.

Figure l is a plan'view showing the tool In operation when the device is used for engaging a wire to be stretched and in dotted stretching wire the hook C is caught into and lines the positions of parts when the wire is securely anchored to the post in the Amanner drawn taut. Fig. 2 is a detail View of one of illustrated in Fig. land the wire which is to 95 the levers, havingratchet-teeth thereon. Fig. be stretched is placed in the groove in the 3 is a detail view of the second lever, showing segment ou lever B, and by means of the pivthe spring-actuated pawl carried thereby. otal clamping-jaw K the wire is held to said Fig. a is an end view of the head of the desegment, and by swinging the lever B into the vice, showing the jaws wide open. position illustrated in dotted lines in Fig. l 10o 5o Reference now being had to the details of the wire may be stretched and held in taut rethe drawings by letter, A designates one of lation while beingsecured to the postbymeans ofva spring-actuated pawl carried by the jaw B, which engages and securely holds the levers from closing until the pawl is disengaged from the ratchet-teeth.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

l. A wire-stretching tool, comprising a lever A, a hook pivoted to the head of said lever, ratchet-teeth on the face of the lever adjacent to its pivotal point, a second lever pivoted to the hook-carrying lever, having a face in contact with said ratchet-teeth, clamping means for holding the wire to be stretched, a pawl carried by said second lever and adapted to engage the ratchet-teeth of the hookcarrying lever, as set forth.

2. A Wire-stretching tool, comprising two levers pivoted together, one of said levers having ratchet-teeth on its face, which is in contact with the face of the second lever, a springactuated pawl pivoted to the second lever, and engaging said ratchet teeth, a curved and grooved segment, secured to, or integral with
